Re: Tinker Board Direct Sampling server
Since I am running a rtl-sdr dongle with only 2M width on my
Tinker Board, I decided to automate changing the bands that I listen to throughout the day. Basically , by restarting spyserver with a different config file
after a pre-determined delay. So the first effort is a simple script that will loop. Next, I will move this to a cron to be more accurate. Jeff (linux hack!) #!/bin/bash

Re: New SpyServer optimizations and features

Hi Jon,
The Wellbrook tends to have a high output on the lower frequencies. You could try adding something like a 100pF capacitor in series with the RF feed to the RTL-SDR as a very crude amplitude equaliser. This will roll off the gain at 2MHz by about 20dB and 1dB at 30MHz but will still be OK for MF reception as the natural noise floor tends to dominate on the lower frequencies. If the attenuation is to much try a slightly larger value of capacitor until you find a happy compromise. Here's a link to an online attenuator calculator. https://www.everythingrf.com/rf-calculators/attenuator-calculator Regards, Martin - G8JNJ

Re: Good CAT and/or Omnirig Plugin?
There is a CAT plugin for Sdr#, its called sdrsharp-catcontroller
Its been a while, the but when I did try it previously, it worked very well. Presents sdrsharp as a TS50 Find it on Google and/or gitHub 73 de kc1ccr bammi

My experience with previous Airspy purchases from Itead has taught me that it's very well worth taking the gamble regarding any import duty and VAT etc

Wow! Still won't be long and then the Wellbrook will be put to good use....
1623 installed and running, just a few tests now. Thanks for everything Youssef.

As for an attenuator, oops, not got one....Time for some more home brew building. Anyone got any good designs that I can knock up? Still the HF+ will be here soon... VHF from Weston super Mare will be online later (87.50MHz through 150MHz). BW Jon

But if it goes wrong don't expect Moonraker to help you. Still there's always the R&D&manufacturing in China ;-(

Yes but when customs get the incoming parcel they will add 5% duty to the HF+ price
and then 20% VAT to the total including the duty and shipping cost ..... So the actual price will be closer to $199 + 5% is $209 then $209 + $24 shipping (DHL to UK) + 20% is $280 which amounts to around 238 euro putting Wimo about the right mark for FULL price i.e. no discount coupons (however without shipping cost) The biggest uplift comes from Moonraker as $280 (which includes shipping) equates to £213 but Moonraker's standard price is £230 (without shipping). It follows that buying direct from itead.cc looks at present the best deal for the UK.

I'm not complaining, just commenting on the situation.

Hi Jon,
You can't adjust the gain in direct sampling mode. The only fix is to put an attenuator between the antenna and Dongle. Regards, Martin - G8JNJ
